To specify a local host or network to be allowed access to the IPSec tunnel, complete the following
steps:
1. Click IP Address.
2. Specify whether the interface is inside or outside by choosing one of the interfaces from the
drop-down menu.
3. Enter the IP address and mask.
4. Click Add.
5. Repeat steps 1 through step 5 for each host or network that you want to have access to the tunnel.
6. Click the Next button to continue.
Step 6: Specify Remote Hosts and Networks
Identify hosts and networks at the remote site to be allowed to use this IPSec tunnel to communicate
with the local hosts and networks you identified in Step 5. Add or remove hosts and networks
dynamically from the Selected panel by clicking on the >> or << buttons respectively. In the current
scenario, for PIX 1, the remote network is Network B (20.20.20.0), so traffic encrypted from this
network is permitted through the tunnel.
